How's everyone getting on with their ignition maps? I've tuned for leaner than stock AFR at cruise but regardless of timing I can't seem to get sensible fuel economy. My old table further up this thread works fine still but my MPG has gone from (UK) 24-27 around town on the stock ECU to ~19 regardless of anything. Running out of ideas.

If you're talking about city MPG, I would say that TPS/MAP accel enrichment is the main player. Be sure that small change in TPS/MAP do not trigger AE more than needed. About this, I'm now using the EAE and it's working fairly nice. Even with some big changes in MAP, the AFR stay flat. I highly recommend trying to use it.

Cheers Sam, sorry for missing this, the forum doesnt email me any more for some reason so hadn't spotted your reply, unfortunately you're running a completely different version of the MS to me - no EAE on MS1, the closest it gets is RPM based AE, which I'm using, with a fairly high trigger thresh, it doesnt trigger with fairly normal changes in cruise speed, it only triggers with stabbing the throttle.

This needs a friendly pump. Anyone using the the MSPNP on an alltrac with stock everything? Anyone try the knock board?

I ask cause I am considering try to use the MSPNP on my trac in the near future and while I have a stock harness I can hack up a little, I would like to keep costs down and just use stock ignition instead of getting COP, trigger wheel, etc.

So I'm VERY new to Megasquirt but I had a question about the 24-1 crank sensor issues. I seem to remember reading something recently about the issue being fixed...is that true? I"m looking at doing a DIYPNP MS2 for my gen 3 swap and want to make sure I understand EVERYTHING before I spend my money on it. I'm not looking for anything crazy right now, I just want to tune my engine to run a bit better since it's currently running pig rich!
